Best Irons for a Penetrating FlightFrom measured launch angle, spin and max height, I picked five that are lifted by spin

Updated: Nov 3, 2026Contains affiliate links

You changed irons, yet the ball still does not fly. That trouble can be told apart by launch angle and spin.

I average a score of 72 and play 150 rounds a year. I picked these seriously.
Same person, nearly the same swing speed, 7-iron. Launch angle still ran from the 18s to the 21s, a full 3 degrees apart depending on the iron.
A low launch that the spin lifts: that's a penetrating shot (I wrote up how it works in How to hit a penetrating iron shot). This ranking is of irons that came close to that shape in the numbers. As a gear nerd, I picked five from the measured values of launch angle, spin, peak height, descent angle and ball speed. I ranked them by how my own 7-iron shots went. I praise the good parts freely, and I say so when something is weak.No. 1 is the Srixon ZXi7 (2026). Of the three I hit, it stretched the most.

Best irons for a penetrating flight: bottom line

I ranked them by whether the ball stretched on my own 7-iron

I decided the ranking by whether the ball flew when I hit the 7-iron. I hit three: the P7CB, T100 and ZXi7. I did not hit the B-FORGED 100CB or the 242CB+, so I have left their positions as the order of masa-golf's numbers.

To read those masa-golf numbers, I made one yardstick: how do you measure a penetrating shot with numbers?

If you know the ball speed and launch angle, you can calculate the height the ball would reach with no air (the vacuum height). Divide the actual max height by that height. The larger this multiple, the larger the share that was lifted by the lift from spin. In other words, the ball is rising and penetrating (in this article I call it the "lift ratio." It is my calculation).

For a PGA Tour player's 7-iron, this lift ratio was about 2.6x. A ball that would reach about 12 m with no air climbs to 31 m.

The table lists five measures.

• Launch angle: the lower, the closer to the shape of a penetrating flight
• Spin: the more, the greater the lift
• Max height and lift ratio: how far spin lifted the ball
• Land angle: the larger, the better it stops on the green
• Ball speed: even if it penetrates, a slow ball does not go far

The measured numbers come from the TrackMan measurements on masa-golf, an individual's site in Japan. They are with a 7-iron, at a head speed of 37–39 m/s, with the same brand of ball. I narrowed the field to irons with a 7-iron loft of 31° or more, because the stronger the loft, the less spin, and the less likely the ball is to be lifted by spin.

The Five by Launch Angle, Spin and Lift Ratio

Launch angle, spin, max height, land angle and ball speed are TrackMan 4 measurements by masa-golf (7-iron, averages). Max height is converted from yards to meters. "Height with no air" and "lift ratio" are my calculations from ball speed and launch angle. ◎ marks the best value among the five. Head speed differs slightly: 38.9 m/s for the 100CB, 38.7 m/s for the ZXi7, and 37.4–37.7 m/s for the other three. Lofts are each maker's official figures (for the P7CB, the figure given in the test article).

I ranked by my own results, so the order in this table is not the order of the numbers.

The average of the irons this site has measured is a 19.7° launch and 6,143 rpm. The P7CB, 100CB and 242CB+ launch lower than that average. The ZXi7 and T100 launch higher, with spin above the average. Even with the same "spin going in", the ball flight is different.

Why This Order

The reasons use only the numbers in this article and the results of my own shots. This is not a best-seller order.

What I looked at first was whether the ball flew when I hit it. For the three I hit, I used my own numbers; the two I did not hit stay in the order of masa-golf's numbers. If the viewpoint changes, the ranking changes too. Please re-read it by the viewpoint you look at first.

No. 1 to No. 5: praise and weak spots

No. 1: Srixon ZXi7 (2026). The one that stretched most when I hit it.

On my 7-iron it climbed to a 30 m peak and carried 159 yards, then moved forward after landing. Of the three I hit, this is the one that stretched.

In masa-golf's data too, its peak height (33.1 m) and descent angle (51.8°) are the best of the 5. Spin is also high at 6,388 rpm, and ball speed is fast at 52.2 m/s. The 7-iron is 32°, and a 6-iron set is ¥171,600.

The shaky point is that it is hard to stop. The spin on my 7-iron was 6,150 rpm, 350 rpm less than the P7CB's 6,500 rpm (6,500 − 6,150, my calculation). With less spin, it is a shape that is said to resist wind but be hard to stop (a general point).

It also came fifth on this article's first yardstick: its 20.9° launch is the highest of the five and its lift ratio is 1.87x. It isn't a low launch lifted by spin. Still, when I hit it, the ZXi7 was the one that stretched most.

Great for you if you

• You want a ball that holds up in the wind and keeps moving forward after it lands
• You hit down and take long divots

I wrote about choosing between it and the ZXi5 in ZXi5 vs ZXi7.

No. 2: TaylorMade P7CB (2024). Good numbers. When I hit it, middle of the pack.

In masa-golf's data, the launch is a low 18.7°. The spin is a high 6,793 rpm. A low launch and heavy spin come together. Normally the two trade off. Stand the loft up and it launches lower but loses spin; lay it back and it gains spin but launches higher. The P7CB's 7-iron is a lofted 33°, yet it still launches in the 18s. That's what's remarkable about this one.

The lift ratio is 2.05x. A ball that would reach 13.5 m with no air climbed to 27.6 m.

When I hit the 7-iron, I got 6,500 rpm of spin, a 29 m peak height and 156 yards of carry. The peak was 1 m lower and the carry 3 yards shorter than the ZXi7 (30 − 29, 159 − 156, my subtraction). A ball that hit toward the toe and went right lost 6 yards of carry. The sound was low, and the feel at the center was good.

There are three so-so points. First, distance. Carry is 153.9 yards, on the short side among the five. The land angle is 48.2°, smaller than the same site's average (49.2°). And I have not been able to confirm the loft and price on the official Japanese site. The 33° is the figure given in the test article.

Great for you if you

• Your ball climbs too high and loses to the wind
• You want to hit a chosen height more than you want distance
• You like forged soft-carbon-steel cavity backs

No. 3: Bridgestone B-FORGED 100CB. It stretches, and it goes far.

The lift ratio is 2.03x, almost the same as the P7CB. On top of that, its 52.5 m/s ball speed and 163.7 yards of carry are the best of the five. A penetrating flight without giving up distance. This is the only one that answers both. It is a current model that only came out in Sep 2026, and the 7-iron is 32°. It is a one-piece cavity back forged from soft carbon steel.

I will also write the shaky points. The spin is 6,064 rpm, almost the same as that site's average (6,143 rpm) and 729 rpm less than the P7CB. And the clubhead speed in the measurement is 38.9 m/s, faster than the P7CB's 37.7 m/s. That difference is included in the gap in ball speed and carry. I did not hit it, so this ranking stays in the order of masa-golf's numbers.

Great for you if you

• You want a penetrating flight but do not want to lose distance per club
• You want to play the newest model
• You are moving from irons with a 7-iron loft of around 32°

I cover the differences between the 100CB and the hollow-body 200CB+ in B-FORGED 100CB vs 200CB+.

No. 4: Bridgestone 242CB+. The biggest lift ratio.

Its 18.2° launch is the lowest of the five and its 2.10x lift ratio is the biggest. On shape alone, it's the best of the five at stretching. It's a previous-generation model from September 2024, and the list price of the 6-iron set was ¥145,200. Prices have come down even for new ones (see the price box below).

The reason I put it 4th is the height. The peak is 27.2 m and the landing angle 47.3 degrees, both the smallest of the five. It flies far, but it does not come down from above. This is the shaky part. It may not be enough for people who want to stop the ball on a hard green. The 7-iron is 31 degrees, the strongest loft of the five. I only looked at it in a shop, so this ranking stays in the order of masa-golf's numbers.

Great for you if you

• You want a low, strong ball that keeps your distances consistent on windy days
• You want to buy a previous-generation model cheaply

No. 5: Titleist T100 (2025). Heavy spin. But it doesn't stretch.

6,667 rpm of spin is the next highest after the P7CB. The descent angle is also 50.4°, so it stops. The 7-iron is 33°, and the official 6-iron set is ¥178,200.

When I hit the 7-iron, I got a 29 m peak height and 158 yards of carry. The gap from the ZXi7 was 1 yard of carry and 1 m of peak height (159 − 158, 30 − 29, my subtraction).

I put it fifth because it doesn't stretch. Launch angle: at 20.7°, it's 2 degrees higher than the P7CB, and its lift ratio is only 1.87x. It isn't lifted by spin so much as it launches high from the start. Its ball speed (50.2 m/s) and carry (152.3 yards) are the smallest of the five. That's a weak spot too.

Great for you if you

• You would rather have the ball stop on the green than penetrate
• Your woods and wedges are all Titleist

I summarize the differences from the previous model in 【Nov 2026 Update】T100 Irons: 2023 vs 2025 Model.

The Numbers for Three That Missed the Five

I will also list the irons I considered but left out of the ranking.

• Titleist T250: its 2.11x lift ratio is the largest of everything I calculated this time. Launch 18.3°, ball speed 52.1 m/s. But its 7-iron is 30.5°, short of the 31° cutoff. Its spin is also 6,020 rpm, below average.
• Titleist T150 (2025): lift ratio 1.88x, spin 6,325 rpm. Almost the same shape as the T100. I put the T100, which spins 342 rpm more, in the ranking.
• Srixon ZXi5 (2026): spin 6,660 rpm, max height 35.7 m, land angle 53.4°. Its height and stopping power are the best of everything I looked at this time. But its launch is 21.2°. It is not a ball that penetrates, but one that climbs high.

What to check for ¥0 before you buy

Even if you change irons, the ball will not penetrate unless your strike changes. First, look at two things with your current 7-iron.

1. Launch angle. At a range or big retailer with a launch monitor, hit 10 balls with your 7-iron. The five in the table above launch at 18–21°. If yours launches much higher than that, you are adding loft at impact. The strike comes before the equipment.
2. Grooves. If they are packed with dirt, clean them with a brush. That alone brings some spin back.

I wrote about the strike itself in How to Hit a Penetrating Iron Flight. Less loft, from above, slightly below center. Those three.

What I learned hitting the P7CB, T100 and ZXi7

The numbers in the table are from masa-golf's Trackman measurements. I ranked by the results of my own shots, which I write about here. It's the 7-iron at a head speed of 46 m/s, faster than the 37 to 39 m/s in the table, so my numbers and the table's cannot be compared on equal terms.

I hit the ZXi7 and P7CB in October 2026 and the T100 in September 2025, using the shop's demo clubs at the TrackMan bay of a local golf shop's indoor area. I hit 20 balls each with the ZXi7 and P7CB, and 15 with the T100.

The ball that flew was the ZXi7. Its peak height of 30 m was the highest of the three, and its carry of 159 yards was also the longest. The head looked a little bigger than the T100's.

The P7CB had a low sound and a good feel at the center. The T100 also sounded lowish at the center. Both went right when I hit toward the toe, losing 6 yards of carry.

What was hard was that my 5-iron fell short with the ZXi7. I used a utility club and filled the gap with a 21-degree.

What I hesitated over was distance versus forgiveness, and what decided it was carry and height. The candidates I compared were the P7CB and the T100. I can recommend it to people with a clubhead speed around 40 m/s.

Even for the same model, masa-golf's numbers and mine differ a little. The ZXi7's peak height is 33.1 m in masa-golf's data and 30 m in mine. I kept the table numbers as masa-golf's and decided the ranking with my own numbers.

Translate it to your own head speed

The numbers in the table are for a 7-iron at 37 to 39 m/s with the same ball. At a different head speed, launch angle shifts by 1 to 2° and carry by a few yards. Read the 18° to 21° range as a rough guide.

The landing angle is 48.2° for the P7CB and 49.2° for the B-FORGED 100CB.<br class="pb">Irons with strong lofts launch lower, so the ball tends to climb less and stop less on the green (general rule). On the other hand they hold up in wind, which helps on a day with a headwind.

People often swap a set for how it stops or how it feels rather than for distance (general rule).<br class="pb">Before you buy, think about whether it will stop on your usual greens rather than whether it will carry farther.

Three criteria for choosing an iron that makes the ball fly

There are three criteria. The first is peak height and carry: of the three I hit, the ZXi7 gave 30 m and 159 yards. The second is how misses show up: the P7CB and the T100 lost 6 yards of carry on toe-side hits. The third is how easy the club is to address.
